How many dB of ambient noise are blocked by the Shure E2 sound isolating ear buds?

These do not use electronic noise cancelling, so the attenuation is all mechanical, and very dependent on the user's selection and fit of the earpiece "sleeve" in each ear. Moreover, the amount of attenuation varies by frequency (the loudness of bass, midrange, and treble components in the ambient noise), and by duration of amplitude (a gunshot peak versus constant jet engine noise). Best way to determine if "enough" noise is blocked is to try them, rather than rely on numerical units such as dB (which can be weighted flat on the "A" scale, to a hybrid "B" scale now seldom used, to the "C" scale that approximates the frequency response of the human ear.)

If I remember correctly they are around 25db. (About the same as ear plugs)That's assuming that you have a snug fit.

i would use something that has an active noise canceling function (requires a battery to produce a noise canceling "counter sound wave"). MEEs will cut out ambient noise well - but not well enough for the high dBA from mowing - i think.

These are attenuating earphones, not noise cancelling so they do just what you asked. I use the yellow 12mm foam tip as I find they do the best job of sealing, thus blocking outside noise and bringing out the full sonic quality of these earphones. I use both the HF5 and ER-4P models.

No experience with Android; but these headphones, with no audio sent to them, block about 70% of ambient sound, via just the over-the-ear design. Turn on music to the headphones and all but maybe 2 or 3% of the sounds outside the headphones are blocked out. Also, they are comfortable to wear for extended periods.

Being that these are on ear designs the size of your head will make a difference on how tightly the bands press the pads against you therefore changing the results slightly. That being said using my iPhone as the music source you have discernible leak around 60-70 % of the max volume around two feet away. Anything beyond that people will definitely hear the music. I would say a 7/10 rating for on ear headphones. Now at blocking noise the results are as follows; with headphones on and no music ambient noise is reduced around 30-40%, when music is introduced at 30% the ambient noise is undetectable. A rating of 5/10 for on ear noise blocking. Hope that helps.

I don't find that it blocks sound very well. I use it to listen to music on my smartphone while walking, and I can still hear other noise with the earphones on. They work well enough for my purpose, though. Not as good as Bose...

I played 'Bell Bottom Blues' from Derek and the Dominos at full volume. The quietest passages were averaging 55 dB and the louder ones 80 dB. Measured from 30 cm or 1 foot from the XBOOM using an iPad Air for a source. I can't speak to if this will work in your situation.

Look at the graph in the upper right in the link below. It is labeled "isolation." There is little noise isolation in the lower frequency range (bass), but very good noise isolation in the higher frequency ranges (midrange and treble). http://www.innerfidelity.com/images/Monoprice8323.pdf

Yup, unfortunately any kind of sound isolating mechanism will create this thump. Even the $550 E500's. There's no way around it. I sometimes where just regular ol' ear plugs, and even with those my footsteps also generate the same thump.All I can tell you is that these earphones are probably more for sitting and enjoying, like on an airplane, or at work. Not so much for walking or running.

These earplugs only cut off about 10 db, but they do it without changing the sound you are hearing.I can still talk to people with these earplugs in, but when the music starts getting around 100 db or more, they keep the loudest parts of the sound from hurting my ears. However, remember if you are somewhere where it is 105 db, you're still getting 95 in your ears.p.s. they are very comfortable to wear and virtually invisible. I don't like the audience to know that I am wearing earplugs.

These are not *ACTIVE* noise cancelling headphones, but they do a pretty good job of blocking out ambient noise as long as you don't rest your head against the wall of the plane (window seat). [In that case the direct physical sound conduction is noticeable]. I use them on airplanes and I can run my audio volume at half and listen quite comfortably. By comparison, my ear buds require nearly full-blast volume on a plane and the audio still isn't clear.

The sound isolation is pretty great. Nobody can ever hear what I'm listening to, and at mid to higher volumes I can't hear anything around me. Once you turn the volume down pretty low, you can hear outside noise, but for the most part they cancel noise ridiculously well for the price. Comparable to headphones that cost twice as much and more.

If you want noise isolation, look into sennheiser 280. They were too boomy for my tastes, and squeezed your brains out of your head.

I used a pair like these, with passive noise cancellation, on a plane and they were actually pretty good. It will not stop the ear pressure due to altitude, but you wont hear a thing

I'm not sure if noise isolation is the same as hearing protection, but I do use them when operating my riding lawnmower and my gas chainsaw, and that sound is minimized to where I can hear and enjoy music from my ipod. When the music is not playing the sound is lessened so much that many times I have to pull out 1 plug so I can tell when the chainsaw/mower starts so I can adjust the choke to complete the start.

I would say they block about 90% of outside noise. However when listening to it loud people next to you will hear your music. For the money you can't beat these headphones.
